PVC yas pellets yog cov khoom siv dav dav thiab yog ib qho ntawm cov khoom siv dav hauv ntiaj teb. PVC muaj cov khoom zoo xws li lub teeb yuag, tsis muaj toxicity, nplaim hluav taws kub rwb thaiv tsev, tsis muaj dej tsis kam thiab corrosion kuj, thiab yog rhiab rau lub teeb thiab kub. Cov khoom yuav tsum tau hloov kho los txhim kho nws cov kev ua tau zoo, thiab nws tuaj yeem ua tiav rau hauv cov khoom tiav tom qab thawj plasticization los tsim PVC yas pellets. Nws yog tsim los ntawm kev sib ntxiv ntawm PVC resin hmoov, plasticizers, lubricants, fillers, pigments thiab lwm yam khoom los tsim cov khoom semi-tiav ntawm thawj plasticization. PVC yog cov khoom siv hloov kho. Raws li cov khoom lag luam xav tau, ntau yam khoom pabcuam tuaj yeem muab ntxiv los txhim kho kev ua tau zoo, xws li toughness, ductility, impact resistance, UV resistance, high temperature resistance, cold resistance, weather resistance, etc. PVC yas pellets nrog ntau yam khoom siv.
